STOCKING ATTACHMENT FOR BINDERS.

Application filed February 10, 1927. Serial No. 167,272.

My invention relates to improvements in stocking attachments for binders, which has for its particular objects the provision of means whereby grain is delivered from the lmottcr oi the binder into a basket and from thence to form several, sheaves into a stool:

Wl'llCll is removed from the basket and lowered into standingposition in the stubble, such action being attained by arranging the stool: grappling mechanism to move rearwardly oi the machine when releasing the stock, at a speed coincidental with the forward movement of the machine so that the stook relieved of horizontal momentum and is in consequence also relieved of any tendency to fall over on being released from the machine. Further objects are to eliminate all hand labour during; the stooking and to provide for the stocks being arranged at predetermined intervals apart on the field, so that the labour of collection prior to separating is reduced to a minimum.

The invention consists essentially of an elevator which receives the sheaves from the binder and deposits them singly into an open basket which is mechanically closed on the actuation of a tripping device, which in turn is either manually or automatically operated, and means for removing the stool: from the basket and de iositing it in standing posi tion to the rear of the machine, as will be more fully described in the following specification, in which Fin. 1 is a plan view of the stooker, with the elevator mechanism and the grappler mechanism removed.

the letter A consists of an A shaped member A having at its apex a universal joint 13. by which it is adapted for connection to a suitable part of the hinder, the base of the mem ber A being secured to longitudinal side frames A and'A each of wiicli comprise horizontal members suitably braced by curved or other stays. The side frames A and A are connected together by a rear wheel mounting A in which a universally pivoted The frames A and A are cross connected zit-intervals with transverse members A, A and A", and a for ther horizontal frame member, indicated by A, extends from the apex of [i to the side 'rame A Extending upwards from the transverse member A is a support A which rises above the upper horizontal members of the side member A and A as at A from whence it is carried downwards and then extends in the same horizontal plane as the said horizontal members.

The forward end of the lower member of the side frame A, see Figure 2, is provided with a hinged bracket A which pivotally supports a jaw A having an inward e:-;tcn

sion A to which a trip cable 1 in a daptcd to be attached, and having also a sheave A at its upper end. Pivotally mounted for vertical movement in the jam A is a swing arm A which is adapted when operating the stooker on automatic tripping, to extend outwards from the side frame A" at an angle of 90 degrees, so that as each previously dcposited row of stooks is reached by the stooker the swing arm strikes the stock and is swung about its pivot, thereby exerting a tension to the trip line A. A line A extends from the swing arm A over the sheave A and is conducted over a suitable arrangement of devices, not shown, to the operators seat to enable him to raise the arm out of engagement with the stocks when desired and to fasten it. Supported above the horizontal frame members A and A is a furthcr side frame A con'iprising rail:-; and stays gonoraliy similar to the side frames A and A1 whicn frame is disposed on the binder side of the stookcr between the basket and the clcvator rcchanism. Extending across the membcrs A are a pair of longitlulinal mcmbcrs A which are adapted to form a bur-1c, for the elevator mechanism. Journallcd between the side frames A" and A" is a bull whccl shaft A The sheaf or bundle elevator consists of a pair of frames B having front legs 1% and rear legs 13 the word front being used to indicate that portion of the elevator which faces the binder. The upper ends of the frames each support an inclined crescent shaped bracket- B", these brackets are connected together by a bar B at thcir upper end and by a shaft 13 at their lower end, they also support a sheet metal table 13". llxlcuding from the bar B is a curved shield ll formed of strips of material spaced apart, see Figure 6, which connects at its lower cxtrcmity to the rear frame legs 13". Extending bctween the legs B and B are lnaccs ll" and B, the braces B being connected by a rod 13, which forms an upper support for a lower shield B comprising curved strips of material. spaced apart in a similar manner to the shield B the outer end of the strips being connected to a further bar B supported on a )air of braces B erected on the frame members of the machine. The lower portion of the shield B adapted to lie in a plane bolow that of the bar B so as to form a suitable receiving pocket for the sheaves as thcy are delivered from the binder. Pivotully mounted upon the bar B are a pair of curved tripping levers B which are :ulaptcd to extend on opposite sides of the kicker of the binder and when actuated thereby, to move a trip rod B through a link B and a counter 10- ver l as shown. A pair of bearings l3 are supported. on the legs B in which short aligned shafts B and B are journallcd, these shafts are connected together by a pair of cranks 22 having an elongated crank piu B The shafts B and B and their associated parts are driven by mitre gears B one of which is keyed to a suitably join-nailed shaft B, see Figure 1, which in turn is dri vcn from the bull wheel by a suitable clutch i11ccl1 auism, which will be describm'l later. Pivotally connected to each of the braces ll" are bcll cranks B which are connected at one end as at B to one end of a rod B and at the other end as at B to a rod B. B indicates a plurality of lower tines, which are adapted to project between the vertical. spaces of the shield B and to describe the movement lit) shown in dotted line in Figures l and 5. These tines are connected together by a bar ll, the outer pair are journalled on the elongated crank pin l3 and are provided with a rearward extension ari'n l3 connected to the lower end of the rod ll. 'lhe lowerend oi the rod 13 is also journalled upon the crank pin B so that as rotation is imparted in an anti-clockwise direction as view d from the :trentot themachine to the saatts B andll the tines are caused to project through the spaces oi? the shield and lift up any sheaves l3 controlling the sheaf distribution into the basket. Extending between the upper portions ot the traxneslfi is a suitably journ alled shaft B having a plurality of upper tines B projecting through the spaces in the upper shield 1%, which tines are spaced apart by separators B 9. At one end of the shaft B a. double grooved sheave B is keyed. On the outer end of the shaft l3 is a crank l3 having operative engagement with a cable rod 13. Extending from opposite ends of the cable red are a pair of cables l3, each leading around one of the grooves of the sheave B in opposite directions and having their outer endssecured to the sheave, so that the rotation of the crank 13' imparts partial rotation in opposite directions to the shaft B and causes the upper tines B to receive the bundles or sheaves as they reach the upper limit of their elevation on the lower tines B see Figure 5, and to swing them around the upper shield ii and :tiually deposit them on the table 3 Turnbuckles B will preferably be provided adjacent opposite ends of the cable rod P) as a means for adj usting the cable l3 so that the upward movement of the upper tines ll will con'nnence with the con'inienceinent oi" the downward movement of the lower tines l3. Freely mounted on opposite ends of the shatt B are a pair of slotted distributors B which are cross connected by a plate B :torming a hinged extension to the table B and endwise movable in the slots of the distributers are pairs of rollers B between which a further plate B extends. forming a bundle spreader. The outer rollers B ot each pair is mounted on a rod B which extends beyond the distributers B and is pivotally connect ed to apair of rocking arins generally indi cated by B. At the outer endot the plate or arm B consists of a lever B h bundle spreader B is a rod having a plurality of spring tensioned lingers 13 which in1- pose such resistance to the bundles or sheaves as they slide downwards along the table B the extension l3 and the plate B, as to bring them into alignment with the edge of the plate ll before the resistance of the spring tension is overcome and the lingers are depressed to allow the bundles to tall into the basket. Rockingly mounted on opposite ends of the shaft B are bell cranks i3 having legs B and B, the outer ends of the legs B are connected to the connecting rod l3" and the outer ends of the legs 13 are provided with a stop B A red i5 connects each leg B intermediate its length to an arm B which is roclriilgly mounted on the rod 13 at the lower end of the table l'l" this arm is hingingly connected at its outer end to the rocking arni L as at B The rocking arm l3- provided with an extension B which is ad: ed to engage the stop ll of the hell crank ll during the time that the distributor mechanism is downwardly extended. F or the purpose of rnaintaining a suitable upward strain upon the distributors a coil spring B is interposed between each rocking arm 13 and its arm it. [is the wheel 13 is rotated the bell cranks ill will. be rocked through an are by the connecting rods B", the bundle spreader ll will be moved lengthwise oi the slotted distributor ll, thus allowing the sheet" '0 fall tltieretroin at varying distances from the table B enabling the sheaves to be evenly distrilnited into the l'asket prior to forming into stocks. During the cycle of l'novenient of the grappler mechanism it is necessary that the distributor table l3 and its associated. parts to be u 'iwardly swung about the shaft ll to remove it from the path oi travel oi? the grappler inechai'lisin, and also to prevent the dropping oi any sheaves from the table B (hiring the closing of t basket and the reinm al therefore secure a disc B upon the bull wheel shatt it having a double grooved. roller or crank pin ll which during part oi the rotation oi. the disc is adapted to engage a collapsible arin generally iiulicated by ll, which arm is keyed to a rocking shailtl3 extending tI'ZUlSVQl'ESOlY of tlie stooker frame to the elevator frame B yed to the shaft 1% and curved at its outer end to an arc coinciding with the path of travel of the roller 13 as at B. At the inner end of the curved portion the upper end of a segment 13 is 'iivotally cruinected, its lower end being connected as at B to the outer end of: an arm 13 pivotaily connected to a tame member. The disc 1-3 rotating anti-clockwise see l igures l1 and 13: brings its roller H first into contact with the arm ll raising it, and through the segment the stookthere 76111. I

B raises the lever B to the limit of its rocking movement imparting clockwise rotation to the shaft B During the subsequent movement of the roller the segment B and the curved portion 13 are engaged thereby, but their relative positions remain unchanged until the roller passes out of con tact with the outer end of the curved portion B when the arm B collapses and falls, allowing the shaft B to rock in an anticlockwise direction to its previous position. Therefore, according to the present timing of the movement the shaft 13 is quickly moved throughout its stroke in one direction and is there held for a predetermined period, when it quickly resumes its former position and again remains stationary until the commencement of another cycle of the disc B. At the elevator end of the :shaft B a lever B is keyed, which engages at its free end, through a rod 13,, a suitably fulcrumcd lever B, the outer end of this lever is connected by a rod B to a link 13 Keyed to the shaft- B to which the distributer plate 13 is fixedly mounted is an arm B having a lip 13" projecting tangentially therefrom, which arm is connected to the link 13 by a pin B During the major portion of the up or down movement of the rod B and the corresponding swinging movement of the distributer plate B, the link B will be in contact with the lip B" of tae arm B The action of the springs B during the lifting of the plate B will exert sufiicient force through the rocking arms B to throw the table beyond its top centre and as the table is brought down on the reversal of the movement of the rod B its movement will be resiliently retarded by the tension of the springs B and finally stopped by the inner ends 13 ofthe rocking arm B coming into contact with the stops of the bell crank levers B so that a slight upward movement of the rod B beyond the actual requirement will in no way impair the effective operation of the distributor table and its parts.

The sheaves after leaving the distributor plate 3 fall into a. basket generally indicated by C see Figs. 14: and 15, which is mounted on trunnions C extending from a pair of opposed curved frame members C and which are suitably fnlcrumed between the main frame members A and A The basket C is formed with bottom wall C secured to the curved frame members G which is provided with a plurality of elongatcc apertures C the purpose of which will hereinafter appear. Mounted upon one end of the basket is a curved rear end wall C com prising a plurality of prongs C and hingedly connected from the opposite or forward end of the bottom wall C is a front end wall C having similar prongs. Secured to the front wall C? is a depending arm C which is connected at its lower extremity to one end of a red C, the opposite end of said rod being pivotally connected to one of the horizontal members of. the frame so that as the basket is turned in an anti-clockwise direction or from the position shown in Figure 15, the bottom wall C will. assume a substantially vertical position, the rear wall will hecome substantially horizontal and the forward end wall will be opened out well beyond the bottom wall position and will come to rest in an outwardly inclined position. so as to permit the free entry of the falling sheaves. The basket is provided with a pair of side walls C which are hinged to the side edges of the bottom wall C Secured to each curved frame member C is a curved brace C the upper end of which is turned over as at C to form a support for a bell crank 0 shown in plan in Figure 16 which is fulcrumed thereto by a pin C Suitably mounted upon the stooker frameis a transverselv rocking shaft C provided at one end with an arm C which extends forward and is adapted to be engaged and disengaged by the double grooved roller B on the disc 13 as it is rotated, the path of travel of the roller is shown in chain dotted line in Figures A and 15. On the shaft C" a pair of cranks C is mounted, one on either side of the basket C each of which is connected at its free end to a rod C and which also is connected to a brace C as at C. l\'l.ountcd upon the outer end of each of the rods C is a segmental guide C, which is provided with a plurality of apertures C for the purpose of adjustably supporting a pin or stop C. In each of these guides and fulcrumcd upon the free end of each of the cranks C is a further crank C which is pivotally connected at its upper extremity to one end of a rod C the other end of the rod terminating in an eye C engaging a leg C of the bell crank C The second leg of the bell crank C indicated by C is connected by a short red C to a staple C secured to a side wall C As the basket is changed from open to closed position by the rocking movement of the shaft C and the consequent movement of the cranks C it will be seen that the free end of each of the cranks C will travel further from the basket trunnion C than the upper end of the crank C hence this crank must move in a clockwise direction until it reaches the stop C when motion will be imparted through the rod C to the bell crank B and to the side wall C to incline it inwardly, thereby compressing the upper sides of the stook therein to a convenient form that it may be removed from the basket and deposited on the ground by the grappler mechanism. By this process of inclining the outer sheaves towards the centre of the basket, the stook when deposited on the ground will remain in a standing position. It will lllfi be obvious that the bulk of the sheaves when in the basket will lie in close fori'nation and that they will require to be spread apart betore the removal oi the stock theretroin. I, therefore, provide a shaft G between the frame A and A upon whichv a plurality of spring tensioued tines C are mounted, which tines are adapted to project through the apertures C as the basket moves to close, the bottom wall C moving across the tines in such. a manner that the base of the sheaves therein is coinbed and spread towards the forward end wall C by the tines. I may provide a cable C to the tines which would lead to a point convenient to the operator for the purpose of withdrawing the tines out of action, it desired. As a means for returning the basket to open position after the StOOli has been removed, a coil spring: is attached by one end to the arm C and by the other end to a suitable trains inoniber.

l rcely mounted upon the shalt A is a bull wheel D from which motion iuiiparted to theseveral mechanisms of the stooher. lvlounted on the binder side of and adapted tor operative engagement with l'l e bull wheel is a clutch generally indicated by il see Fig ure 1? which serves to actuate the elevator mechanism and the basket C Secured to the bull wheel D is an annular ring it having a plurality oi? inner peri 'iheral recesses Fitting over the ring i and freely mounted on the shaft A is an annular clutch casing l ha ving' a peripheral. things E which scr as chain guard for a sprocket wheel ill mounted thereon. The outer periphe. il edge of the casing is provided with a plurality of ratchet teeth E", the purpose of which will hereinafter appear. Carried within the easing is a pair of pins upon which are niountoil trip arnis l'D each consisting of a three lettered bell crank, the being indicated by i l and l5 respectively, and having); an annular recess li the sides of which torni stops for a pawl ll hilt-ruined upon a pin E. A spring ill is secured at one end to the leg it and at the other to the pawl i "for the purpose ot holding; the pawl normally out oil? contact with any oil the recesses it. Mounted on the end closure oil: the casing li is a pair oi brackets lid through each of which a rod E" has slidinp; n'iovcn'ient and which also serves as an abutment tor a com- .pression spring E on the rod. lllach rod E" .is connected to the free end of one of the legs ll" ot F10 hell crank on. trip arin E and to the tree end ot the leg}; E of the other. and is provided with an abutnuuit' collar l tor the spring E it is also provided with a pair ct collars ll secured thereto on opposite sides of a two arined rocking; trip E so that a counter clockwise movement imparted to either of the trip arnisll or E will impart movement to the rods B (one of which iii-av be omitted) and through the bell cranks E vent the clocluvise movement t lever W the upper end (it which is adapted to en "lflG either of tee trip arnis lfi or E to d usage the pawls .l l :lroiu thorecesscs l l and having a spring; latch It extending to engage any off the ratchet teeth E to prethe casing E The trip lever is provided with an adruitable spriu tension E to restore it and its associated parts to normal engaging); position as shown after having been withdrawn. The lower end of the lever E is connected through a bell cranl-i E (also shown in plan in Figure 1'?) to the cable B, see Figure 4;, which is pulled, by the act-ion ot a sheaf as it is kicked troin the binder into the elevator hopper and as it throws down the tripping levers l3.

Secured to the outer face of the sprocket wheel l and. concentric therewith is the disc ll which imparts swinging movement to the distrilnitor table of the elevator through the double grooved roller B previously described. A chain H, see Figure 1, operatively connects the sprocket E with a further sprocket 11]" which is keyed to one end of the shaft B From the above description it will be seen that as each sheaf tlialls into the elevator, throwing down the tripping levers B and causing; the actuation oi. the clutch, that the sprocket wheel E will niah'e a quarter turn, and in so doing will rotate the shaft B and cause the lowe" tines B to elevate the sheaf into the bight oil the upper tines ll, the upper tines then swingingover to deliver the sheaf onto the table B This same movement causes the distributor extension B to move its position, so that each successive sheaf is dropped into the basket in a ditlerent position to that taken by the previous one. The grappler mechanism actuated by the bull wheel D through the medium of a clutch l which is designed to make one revolution every time the grapple]: is tripped, and in so doing to impart a complete cycle oi. operation to the grappler and its parts. The clutch F see Figure 19, consists of an annular ring F having inner peripheral recesses F and which is secured to the bull wheel D Concentrically titted around the ring F is a casin ll, which is secured by its end closure (not shown) to the bull whee-l shaft A. Mounted within the casing l are bell crank: l mounted on a pin. 1? and having; legs F F and F", the legs 1* extending through the periphery oi the casino; and forming a trip arm, the legs F and F of opposing cranks being connected together with spring tensioned rods F in a similar manner to that employed in the clutch E for the purpose of moving the pawls F Mounted on a suitable portion of the frame member A is a semi-circular guide member F supporting a compression spring F which is adapted to bear against a trip lever F pivotally mounted upon the frame, which lever is adapted to engage the trip arm F 7 of the clutch F to cause it to disengage the pawls F from the recesses F of the ring F for the purpose of disconnecting the drive of the bull wheel D from the grappler mechanism and conversely, as the trip lever F is moved by a pulling strain on the cable A or a further cable F which operates through a bell crank F (also shown in plan bracketed to the figure) the trip arm F 7 is released to permit the driving engagement of the clutch F through the pawls F. A light spring latch F is pro vided on the trip lever F which is adapted to engage a set of ratchet teeth upon the periphery of the casing F 4 to prevent its rearward or anti-clockwise movement. The cable F is extended through to a suitable lever or foot pedal on the binder, so that during the first round of the field taken by the binder and its stooker, the operation of the grappler mechanism may be manually controlled by the driver.

The grappler mechanism is adapted to swing about a central shaft G which traverses a portion of the frame of the stooker forwardly and rearwardly which will hereinafter be referred to as the grappler traversing movement, which is shown in Figures 2 and This grappler traversing movement is elfect ed by providing the bull wheel shaft A with an outside crank G on the free end of which a bell crank G having legs G and GA respectively is mounted, the free end of the leg G is connected to the free end of a leg G of a bell crank G journalled upon one of the horizontal members of the frame A as at G, the other leg of the bell crank G, indicated by G is provided with a swinging arm G which is provided with a pivotally mounted slide socket G at its free end. Intermediate the length of the arm G a pin G is mounted to which one end of a rod G is connected, its opposite end being connected to the free end of the leg GA of the bell crank G so that as the crank G is rotated by the bull wheel shaft A due to the engagement of the clutch F the slide socketGr is caused to follow a path as indicated in dotted lines in Figures 2 and 3 and is lettered X.. Rockingly mounted on the pin G is an arm G having con nection at its forward end to a rod G which is actuated from the crank G the rearward end of the arm G actuates a cable rod generally indicated by G Keyed to the shaft G is a double grooved sheave G the spokes of which are shown broken away to disclose other moving parts, this sheave is partially rotated by a pair of cables G which extend from turn buckles G and pass partly around the grooves of the sheave G and are secured thereto. At the outer end of the cable rod (W is an eye G through which a rod (2 is endwise movable, which rod has a stop (1 at one end and is pivotally connected at the other to the rim of the sheave G as at G. The shaft G extends across the machine and beyond the longitudinal frame. members A, A and A and is journalled in a pair of floating bearings G see Figure 1 intermed iately carried in rockers G- In order that a parallel motion may be imparted to the shaft G and the grappler supporting mechanism, the pair of rockers G in which the shaft G is journalled, is suspended on a pair of swing arms G journalled on frame braces as at G and supported on a turtuer pair of swing arms G1 which are keyed at their lower end upon a transverse shal't G journalled upon the longitudinal frame members A and A. A further rocker G having a central pin G is provided towards the rear of the machine, which is pivotally connected to a suspended swing arm G and supported on another swing arm G both of which arms are journalled on the longitudinal frame r 3 as at G and G rcs]')cctivcl v. Freely mounted on the shaft l is a reclining T member generally indicated by G. its horizontal leg G forming a roe connection between the outside rocker G (and also the shaft G and the rocker G the lower T head G is carried vertically down ards and is outwardly cranked to support a pivot pin G and the upper T head G is carried vertically upwards terminating in a pair of hori- Zontal'ly opposed arms G A stillener G- extends diagonally downwards from the horizontal leg G of the reclining T member G passing beyond the lower T member G". where it is bent back at an acute angle to the member G where it is riveted, the apex of the angle therein supporting a pivot pin G which will hereinafter be referred to.

From the above description of parts. it will be readily seen that as the cable rod G is moved in a rearwardly endwise direction the sheave G will be rotated anti-cloclcwise until the stop, G of the rod G is ln'ought into contact with the eve G of the cable rod. when rotation of the sheave will be arrested and the sheave, its shaft G and associated parts will be moved as a unit rearwardly of the machine.

Mounted on the pin G at the base of the lower T member G is a bell crank G having legs G and G, the leg G being prw vided with an eye in which a slide collar G is pivotally mounted. Extending through the collar G is a rod G which is connected at one end to the pin G of the stay G. the opposite end being provided with a stop G forming an abutment for a compression spring G which tends to move the bell crank G in a clockwise direction. Suitably supllll] llll ported from the spokes of the cable sheave G is a rim 6: having a coil spring G around a portion of its peripl'iery, which spring is limited in its expansive movement in opposite directions by stopsGr and G Freely mounted upon the shaft G is a swinging arm G having a pair of pins G forming a fork which entibraces a portion of the rim G the outer end. of the arm is provided with a plurality of apertures G to any of which, according to the adjustment required, one end of a connecting rod G is litted the other end of the rod being connected to the outer end of the arm G of the bell c ank G Freely mounted on the shaft G is a further swinging arm G having a fork G embracing the rim G and which is apertured at its outer end to form an adjustable con nection, as at G, for a connecting rod G Secured adjacent the outer end of the trans-- verse shaft G is a stop arm ti see Figure 32 which is eyed intermediate its length as at G and is provided with an abutment G on its forward edge adjacent its upper end. Note, this movement is omitted from Figure Eh but shown as a detached view in Figure 32. Freely mounted on the shaft G is a trip arm G which is cranked over adjacent its upper end to assume the same plane as the stop arm G. This trip arm is provided with a forwardly extending rod G which projects through the eye G of the stop arm G and spring tensioned therefrom, the outer end of the trip arm is provided with a roller G and the outer end of the rod G is provided with an eye GUS forming a connection to a pull rod Gr which projects freely through the slide socket G on the arm G A stop collar G is secured to the rod tiand is so adjusted that when the arm G is moved to its n'iost forward position as shown in Figure 2, the stop lever G will be actuated and through the transverse shaft G the upstanding swing arms G will be correspondingly moved forward, carrying the cable sheave G and its shaft G to the position shown in Figure 2. W hen the above enin'nerated parts are moved to the limit of their travel in a rearward direction, the stop lever G and the trip arm G are temporarily locked in the position shown in Figure 32 by a latch geneally indicated by G see also Figure 32, and which is supported on a semicircular bracket G mounted upon the lower frame member A Pivotally mounted upon the bracket is a two piece rearwardly curved arm G in which a fm'wardly curved latch G is pivoted, this latch is provided with a tongue G at its upper extremity along which the stop lever G is led into engagement under the bight of the curve, the latch beingadapted to come to rest in contact with the stop G. On the lower end of the latch a spring tensioned trigger G having a limited upward movement is pivotally mounted which is adapted to be tripped downwards on being struck by the roller G of the trip arm G on its rear ward movement and to subsequent 1y hold the roller against forward movement until an appreciable strain is imposed by the roller due to the forward movement of the rod tilwhen such strain tips the latch G in an anti-clockwise direction to release the stop lever G and permit the clockwise move ment of the transverse shaft G. The adjustment of the two piece arm G is eifected by providing a stop G upon the bracket G .fL stron coil spring G is provided between the upstanding swinging arm G and a suitable part of the frame for assisting the forward movement of the shaft Gr and its parts, and also for the purpose of cushioning the final return movement thereof.

Keyed upon the shaft G is a pair of lifting arms i l tween which the grappler is adapted to be moved, these arms are outwardly flared at their upper ends to provide arcuate' tracks formed to a radius from the shaft {1}", and wh ich terminate in a pair of upstauding lnackets (i for supporting shields G shown removed from Figures 2 and 3, and shown in detail in Figures 29, 21, 26 and E28.

Freeiy mounted upon the shaft G is a sleeve fir see Figure 1 having at its extremities a pair of arms G which sup port at their upper ends a grappler shaft G said shaft extending outwards from the arms to form engagement with the track i of the lifting arms G The outer end of the shaft (W, see Figure 2 is provided with a "i" member G having opposed cross arms G which are connected by connecting rods G to the cross arms (P of the upper T member G, so that as the lifting arms G are swung about the shaft G by the cable sheave inovemenh the shaft G of the grappler mechanism is unrotatingly carried about the are described by the lifting arms and is also permitted a furthcr length of travel corresponding to the length of the arcuate track G The path of travel. described by the shaft G is shown in dotted line in Figures 2 and 3, and is designated by the letter Vl it will be understood that since the grappler moveiti'ient is intermittent, and that periods of rest occur when sheaves arc bein transferred from the binder, over the elevator of the stooker and into the basket that the crank G and'the associated parts by which the grappler is moved must assume a predetermined position of rest. The position of rest for the crank G and other parts is indicated by a smail circle and-a letter as follows :crank G as a; inner end of cable rod as 3 sliding block G as av; lower end of rod G as w; upper end of rod G as v and position of grappler shaft G as a.

'As the arm G is moved towards its most forward position so that the slide socket G engages the stop (ar the rod is forwardly moved thus raising the trip arm G to cause the release of the latch G from the stop arm G which permits the shaft G to turn, in parting forward movement to the rockers G and tothe sha ft- G The rotation of the shaft G is as previously stated, effected through the movement of the cable rod G its cables G" and the sheave G The springs and G serve to counterbalance the weight of the grappler the lifting arms G and other associated parts and to hold them when desired in the position of rest indicated by u in figure 3. during which time the fork of the arm G will be in engagement with one end of the .spring G and through this engagement and the movement of the connecting rod G, the bell crank G will impose a compressive strain upon the spring G. lVhcn the grappler is raising its load the rearward end of the spring G will abut the fork G of the arm G moving it in a clockwise direction,

imparting a pulling strain on the connecting rod G and through the bell crank G a gai n impose a compressive strain upon the spring G The position of the several parts shown in figure 3 is that in which they would be immediately prior to coming to rest or in other words that where the trip arm F of the clutch. F is coming into engagement with the trip lever F and is being liited to discounect the drive between the clutch and the shaft A. It will be noticed that the weight of the several parts being off centre at the period of rest that a tendency would exist to rotate the clutch casing F in anti-clockwise direction, but that this is prevented by the spring F" engaging the ratchet teeth F on the clutch casing.

On the inner faces of the grappler shields G5 see Figures 20 and 21, is a series 0 t gu iecs arrang .d in opposed pairs, the outer guide G extending approximately one half oil the length of the forward side of each shield, an inner guide G running parallel thereto, and inwardly curving towards the track G as at G, and also an upper guide G1 in the form 01" a triangular member having a convex front surface G, a concave upper surface G and a concave surface G the triangular memher being pivotally mounted on the shield as at G and resiliently held in position i a spring G whereby the surfaces G and G form a'continuous track. Mounted upon the upper end of each of the lifting arms G is an upwardly spring pressed arm G having a latch G intermediate its length and adjacent the forward. end oi the arcuate track G also having atits outer end a roller G which is adapted to be moved between the guides i and G The purpose of the above mentioned guides and the arm G will hereinafter appear. 7

The ,Qrappler see Figure 23, which is generally designatel by H consists of a frame having longitudinally disposed members H catches H and H respectively, see detail. in

F re 29. the purpose of which will heroinaiter appear. Extending also between the shaft G and the head H is a pair of vertical guides H (shown only in Figure upon which an upper crosshcad 1. is slidably movable. The lower crosshead H is slidable upon the post H". The upper crosshead H is provided at its ends with stub shafts H to which are tilted rollers H for the purpose oi ch nging the guides on the shields of the lifting arms (i for rccipro- (llllllfi the crosshcad H upon the post H.

Between the ends of the longitudinal members H are a pair of transverse shafts ll upon each of which a pair of bales or stool: presscrs mounted on brackets H. are l'iingingly carried. Hingingly connected to each bra hot H is a. trznne H" carrying a plurality of lower tines H the tines H being hereinafter referred to as the gang tines. The gang tines I" 18 and the bales l'l arc flexibly tcusioned apart by rods ll passing through oriliccs in the frame H. as at ll and the central portion oi the bale H. which rod is provided with a stop at opposite ends as at H and between which and the apcrtured portion H oi the tramc H" springs H an d are mounted. so that as the pairs of gang tines H are moved towards each other into the stock, the springs H exert a yielding pre sure upon the bales I; and compress tue head oi, the stook. and rcversclv as the gang tines are removed from engagement with the stool: before the head thcrcol' is released, thus permitting the base oi the stook to sp cad evenly from internal pressure. in such a manner that it will stand erect in the stubble after being finally released.

Hingingly mounted on each transverse shaft H is a cranked double arm ll. see Figure 2%., which extends on opposite sides oi the post H" and is connected at its outer end by a rod H to a gang tine frame H each of these double arms is connected to one side of the cross head by a fork member ll l which, like the double arms H extend on opposite sides of the post H The cross head H to which connection is made to the Fork members H is provided with a slot H through which the spring catches H are adapted to pass freely. The upper cross head H is provided with a pair of bearing blocks H which areshdable upon the guide posts 151". A shaft H extends from opposite sldes of each of the guide blocks H Note, these the weight of the grappler is supported only from the rollers H of the upper crosshead.

The grappler parts thus far described func tion in the following manner.

When the grappler is at rest, as shown :in Figures 22, 23 and 24, the shaft G upon which it is normally supported, is carried at the extreme left of the arcuate track G of the lifting arms G and the rollers H ofthe up per crosshead are at the extreme left of the convex portion G of the triangular guides G on the shields As the lifting arms are carried over in a forward direction the grappler. will maintain its vertical position, the rollers H passing out of contact with the shield guides and following a path as shown in Figure 20, subsequently re-entering the shields, reaching a point indicated by a dotted linecircle and indicated by the letter 6', when both crosshead guidesll and H are allowed to fall freely along the post H and the guide posts H" by means which will hereinafter be described, to the position shown in full line circle and marked H .in Figure 20, the weight of the crosslieads, the bales H, the gang tines H and associatedparts being sufficient to drive thetines H between the prongs of the basket C io engage the stook therein. In this latter position it will be noticed that the shaft G86 having been carried over the centre of the cablesheave shaft G has slid along the arcuate tracks H to their opposite end or the extreme right, and in so doing has de ressed the levers G and has become locked in that position by the catches G thereof. On the return or rearward movement of the lifting arms G the rollers H move along the guides G raising the triangular guide members G and in entering between the guides G and G come into c011- tact with the rollers G of the lever G depressing it far enough to disengage the latches G from the shaft G When this point is reached by the rollers H the arms are at their lowermost position onthe rear or anticlockwise movement, therefore, since the support of the latches G is removed from under the shaft G and the arcuate tracks G are disposed in a substantially vertical position, the grappler, spring supported only by the upper crosshead H is free to fall, its

shaft G sliding without obstruction clownwardsof the arcuatetracks G. The lower crosshead H is held by the spring catches H until an appointed time, when the post H is turned 90 degrees about its axis by a movement to be hereinafter described, thus releasing the crosshead H allowing it to be raised and withdrawing the gang tines I- 18 and the bales H from the stook, permitting it to fall freelyfinto standing position on the stubble. The grappler is unaffected by the further movement of the lifting arm as their move- .ment is continued to the point of rest, except that the rollers H are moving at a constant radius from the shaft G along the guides G to the position shown in Figure 21. The crosshead H is adaptedto slide lengthwise of the post H, depressing and passing over the sprin catches H on its downward stroke and the catches H on its upward stroke, the catches springing outwards to prevent its return n'iovement. The release of the crosshead is effected by turning the post H 90 degrees about its axis so as to bring the catches int-o alignment with the slots H of the crosshead, that it may pass freely over them. This turning movement is effected by fitting a crank H at the base of the post H, which is coupled by a rod H to a spring tensioned lever H? fulcrunied in a suitable position on the grappler frame as at H The free end f the lever H is curved as at H and supports a yoke H? which is adaptedto stand normally with its opening disposed transversely of the grappler frame and which is pivoted upon a pin H and is provided with a recessH" on its rear edge. A. dog H of a trigger H, also carried on the lover I is adapted to engage the recess H to hold the yoke in normal position. Suitably supported from the grappler frame is a stop H which thetrigger H is brought into contact with as the lever is moved over by the grappler trip mechanism. for the purpose of withdrawing the dog from the recess of the yoke and per mitting said yoke to turn at right angles to its normal position, when the lever can return to its starting position as shown in Figure 31. A tension spring H is provided between the trigger and the yoke forthe purpose of first holding the yoke in extended position and after release for holding it in right angular position, sothat it may beagain engaged by the tripping mechanism and restored to, and locked in normal position.

The grappler tripping mechanism is generally designated by J and consists of a pair of ring or plate members J supported by stays J from the outer side members H of the grappler H Rockingly mounted being a horizontal leg J 5 and a vertical leg J the legal?" is slightly curved on its under side as at J to provide a variablepoint of contact forits stop to be referred to later. The upper tween the members J is a bell crank J havtherein, to upset the basket, to spread the.

base of the stook therein and to compress its head in such a manner that it can be seized by the grappler and removed from the basket prior to its being deposited upon the ground in a standing position. The rotation of the,

disc- B and its roller B, and also that of the crank G bemg simultaneous, 1t will readily be seen that all the movement of the separate n'ieehanism will be so a co-ordinated as to bring the basket into upset position during the forward stroke and opening movement of the grappler, to compress the sides of the stock as the gra1L)pler closes about it to lift it, and to raise the grappler and its stook,

swinging it rearwardlyat the same time as tllflwfllfillllbllbfil B 7 is belng lowered and as the basket is being opened intorecelving position. 1
